Those drives are getting very hot and stop responding. Just put a good fan to the PCB and try again.

I know very well this model as well as WD800BB, WD600BB and WD400. WD is using the same chip to interface the heads as in the older models. The chip is "overclocked" because the transfer rate is higher and it is getting really hot. I have seen chips that are burnt out. The change of PCB could not help much...

You're right, I'm in this buisness for more than 10years, but as a hobby. I do mainly disk repair (PCB repair to be correct) not data recovery . The market for repaired disk here is poor, almost dead! And disk prices are so low now.... No one can get rich by doing this job...As most of us.

Hi,
IMHO in that case it would surely click. it looks like a translator problem, but I don't have realy much experience with WDs.
